The Michell Instruments MDM50 Portable Hygrometer makes spot checks of the dew point in air and gases down to -58°F (-50°C) dew point in less than 10 min. This self-contained instrument weighs only 8.8 lbs (4kg). Simply connect your sample gas to the Quick Connect fittings, turn on the instrument, and it will automatically begin to measure the dew point of the applied sample.

The Michell MDM50 Hygrometer has a complete, built-in sampling system that measures the dew point of any air or gas line, at up to 290 PSIG (20 BARG / 2 Mpa) pressure.
The two interchangeable inlet/outlet fittings allow you to choose between dew point measured at atmospheric, or at line pressure, by simply swapping the position of the fittings. An integrated filter housing uses standard filter cartridges and provides 99.5% protection against particles down to 0.3μm. Optionally, Swagelok® tube couplings can be specified to allow operation of the unit at up to 4351 PSIG (300 BARG / 30 Mpa).

The Michell MDM50 features a bright 0.5" red LED display making it easy to determine the dew point of your process even in dim conditions or direct sunlight. Michell also provides a 4–20 mA analog output for connection to a chart recorder, data-logger or computer system, so dew-point trends can be analyzed over time.
